Est. 1899 · National Register of Historic Places · Built by J.C. Milligan — Flagstaff Justice of the Peace and brickmaker · Now houses the Flagstaff Convention and Visitors Bureau
J.C. Milligan — businessman, brickmaker, and at various points Flagstaff's Justice of the Peace — built his family's residence around 1899 at what is now 323 W. Aspen Avenue. The house was designed by architect James M. Creighton and constructed from locally quarried red sandstone and brick. At more than 4,000 square feet, with indoor plumbing and electric wiring unusual for the era, it represented the ambitions of a man who had prospered during Flagstaff's early railroad and lumber economy.
Mabel Milligan, daughter of J.C. and the building's most prominent ghost, was a schoolteacher who lived in the family home while caring for aging parents. She fell ill suddenly in 1923 — fatigue and fever that worsened over days — and died in the upstairs bedroom. She was in her mid-twenties. Her death, attributed to a diabetes coma, came before insulin was widely available as a treatment. Colleagues and students later described her as warm and dedicated.
The house subsequently served as apartments and eventually passed to the City of Flagstaff. It now houses the offices of the Flagstaff Convention and Visitors Bureau, open to the public weekdays from 8 a.m. to 5 p.m. The building is listed on the National Register of Historic Places and features an exterior mural — 'The Ghost of Mabel Milligan' — commissioned to commemorate the property's history. Workers during a 2016 renovation reported unease in certain rooms, and one crew member claimed to have seen a woman in period clothing who disappeared.

Phantom footsteps on upper floors after closingSelf-opening doors on second storyCold spots near former bedroomUnexplained floral perfume scentApparition in period dress (2016 renovation)
The haunting tradition at the Milligan House has developed around a specific historical person with a verifiable death — which distinguishes it from many ghost tour stops where the origin is entirely oral tradition. Mabel Milligan's life and death are documented in Flagstaff historical records: she was a local schoolteacher, beloved in the community, who died suddenly in 1923 from what was likely a diabetic crisis. She was in her mid-twenties and had been living with her parents in the family home.
The reported phenomena cluster in the upper story where Mabel's bedroom was located. Footsteps on the stairs and across the wooden upper floors are heard after the building locks for the night — multiple staff over multiple years have documented this separately. A pattern of self-opening doors on the second floor and cold spots concentrated near the former bedroom are consistent across accounts. Some staff describe an unexplained floral perfume scent, attributed to Mabel's personal preferences.
During a 2016 renovation, a crew member claimed to have seen a woman in period dress in one of the upper rooms who vanished when he looked directly at her. He did not identify himself publicly, but the account was relayed by building staff.
An exterior mural on the building — 'The Ghost of Mabel Milligan,' commissioned by Mural Mice — reflects the degree to which Mabel's story has become part of the building's public identity, acknowledged by the city government that now owns it.
